Yeah someone who wanted to trade with me had one and I wanted it and he tried to rip me off by saying that it was worth 5 refined and tried to get all my weps and hats which is about 3 or 4 pages full with stuff. Needless to say after I caught him out n it after a price check i got Heavy's Football helmet and the pin for about 6 zombie souls and 2 stranges

Now here is a kinda rare item. But you can still buy the soundtrack that includes it on Amazon(Careful, only the CD version includes it, don't buy a used version since the codes will have been used). You'll get the great soundtracks for Portal and Portal 2 on 4 CDs plus a code for the Ap-Sap and a DOTA 2 code including some exclusive items.When the thing is 13$ on Amazon I have no idea why it is that expensive on the Steam market.
